DC Digital High Voltage Meter   DHM(DC)


PDFdownload
The DHM type digital voltmeter has a high input resistance and, like electrostatic voltmeters, measures voltages produced by piezoelectric devices and other high impedance high voltage power generating equipment. This voltmeter offers high accuracy and short measurement time. Moreover, it is small and rugged and virtually unaffected by the environmental conditions. These features make this voltmeter suited for use in production lines as well as in laboratories. Use of GP-IB and USB interface is possible. maximum measurement voltage Accuracy

AC Digital High Voltage Meter  DHM(AC)


PDFdownload
The AC type digital high voltage meter for commercial frequency is small rugged and easy to carry, and digital display makes measurement easy. For these reasons, this voltmeter can be used easily as AC high voltmeter in place of a static voltmeter or a transformer for gauge. Although this size is small, this voltmeter can make measurement to AC 50kV. Use of GP-IB and USB interface is possible. maximum measurement voltage Accuracy

AC/DC Digital High Voltage Meter  DHM(A/M)


PDFdownload
The AC/DC type digital high voltage meter has a high input resistance and can measure voltages produced by high voltage generators with a small output capacity. This voltmeter is small, rugged and easy to carry. Moreover, this easy to use voltmeter allows high precision measurement in a short period of time. Use of GP-IB and USB interface is possible. maximum measurement voltage Accuracy
